The story starts off with the Chipmunks excitedly making plans to spend the day at the water park. However, their excitement is dampened when they learn that Ms. Croner is accompanying them on the trip. Ms. Croner is strict and always spoils their fun, so they decide to rid themselves of her and come up with a plan to ditch her. They pretend to be sick and make their way out of the park under the pretext of going to the doctor. However, things don't go according to plan and they get stuck with Ms. Croner, who insists on taking them to a restaurant.

While the others are enjoying their meal, Simon's conscience gets the better of him and he decides to call Dave and tell him the truth about Ms. Croner. Dave reminds them that Ms. Croner is responsible for their safety and that they need to behave themselves. He also asks them to keep an eye on their neighbor's child, Kevin, who is also at the park. The Chipmunks reluctantly agree to babysit Kevin, hoping that it won't be too much of a hassle.

Things take a turn for the worse when Kevin becomes overbearing and starts tattling on them to Ms. Croner at every opportunity. Kevin is clingy and annoying, which makes it difficult for the Chipmunks to enjoy their day at the park. They try to shake him off but he keeps following them around. They also worry that Kevin's constant tattling will get them into trouble with Ms. Croner.

Meanwhile, Ms. Croner is enjoying herself and seems oblivious to Kevin's behavior. She is having a great time at the park and even joins in on the fun when Alvin challenges her to a water slide race. Ms. Croner's competitive streak comes out and she is determined to win the race.

The Chipmunks decide to teach Kevin a lesson and give him a taste of his own medicine. They start tattling on him to Ms. Croner, which annoys her and makes Kevin realize how annoying his behavior has been. He apologizes to the Chipmunks and promises to stop tattling. They forgive him and decide to have some fun at the park together.

In the end, the Chipmunks learn an important lesson about responsibility and the consequences of their actions. They realize that they can't always have things their way and that they need to be mindful of others around them. They also learn that sometimes, it's better to take responsibility for your actions and face the consequences than to try and get away with something. The episode ends with the Chipmunks and Kevin enjoying their day at the park, with Ms. Croner looking on happily.
